MACHINE FOR MANUFACTURING BOXES.

SPECIFICATION forming part of Letters Patent No. 336,340, dated February16, 1886.

Application filed October 4, 188iA Serial No. 144,687. (No model.)Patented in Canada August 31, 1885, No. 21315.

To all whom, it may concern:

Be it known that I, ALBERT F. MOREE, a

citizen of the United States, residing at Milford, in the county of NewHaven and State of Connecticut, haveinvented certain new and usefulimprovements in Machines for Manufacturing Boxes from Straw-Board,Pasteboard, and the like; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain novel and useful improvements inmachines for manufacturing boxes from Vpaste or straw board, and has forits object to form the edge turned up at the side of the box at aperfect rightangle to the body of the box, and to so strip the boxesfrom the upper die that the shape will be preserved, and, furthermore,to'greatly increase the production by a single machine; and with theseends in view my invention consists in the details of construction andcombination of elements hereinafter fully and in detail described, andthen specifically designated by the claims.

In order that those skilled in the art to which my invention appertainsmay understand more fully how to make and use my improvement, I willproceed to describe the same in detail, referring by letter to theaccompanying drawings, forming a part of this specification, in which-Figure l is a central vertical section of my machine; Fig. 2, a sideelevation, and Fig. 3 a detail perspective, of the faces of the dies.

Similar letters denote like parts in the several figures.

A is a platform, supported on a standard, B. Secured within thisplatform in any ordinary manner is a hardened plate, C, having centralvertical opening, D. XVithin the standard is a hardened ring, E, havinga central opening, F, of the same diameter and nature in crosssection asthe opening D. Vithin this opening F closely rits a die, G, adapted tohave a vertical play-therein. This die is attached to the upperextremity of a spindle, H, which extends upward through the standard.The under surface of the die and the dieseat I are couutersunk orrecessed, as shown at J, to accommodate a coil-spring, K, placed aroundsaid spindle and confined between the die and seat, for the purpose ofgiving a spring action to said die within the ring E.

L is a punch, having interiorly arranged therein a die, M, adapted to bereciprocated vertically within said punch. Nis a seat for said punch,formed in the upper face of the plate', C.

The die M and punch are reciprocated vertically independeut of eachother by means of any ordinary double-acting eccentric or foli lowercams common in presses. Immediately below the plate and through the wallof an internal recess, O, in the platform is an opening, P, whichcommunicates directlyV with an air-blast.

The operation of my improvement is as follows: vThe straw or paste boardis fed in between the punch and its seat. The punch then descends andcuts the blank, forcing it within the seat. kThe die M is now throwndown, thereby cupping the said blank and forcing it down through theopening D against the die G. The latter yields, owing to its springmovement, and the cup or box formed is forced within the ring E, the dieG abutting against the seat I. The die M now returns to its normalposition, and the cup or box is stripped from said die by the lower edgeof the opening D and carried by the air-blast out into any desiredreceptacle. Very often the box will stick within the ring E, and in thisevent the die G will as it returns upward, by virtue of its springaction, throw the box without the ring into the blast. The upper die iscountersuuk, as shown, and the lower die is raised at its centralportion, so that a central depression will be formed in the body of thecup or box for the purpose of giving it additional strength. In myimproved methol no heat whatever is introduced as an agent in preservingthe angular shape of the box; but I accomplish this most desirableresult by forcing the box within the ring against the lower die, therebycausing the angle in which the sides and top or bottom of the box meetto be perfectly sharp. On the return of the upper die to its normalposition the box is always loosened from said die, so that a very slightconcussion against the edge ofthe opening D is sufficient to detach itand allow it to be carried by the airblast.

By using a IOS punch and dies of different shapes, and bycorrespondingly changing ,the shapes of the openings through which saidpunch and dies operate, I am enabled to make any kind of box desired.

By the use of a resilient lower die I am enabled to make boxes withoutforcing them entirely through the ring, as is most frequently done, andalso more boxes can be made by a single machine than heretofore, for thereason that the comparatively short play of the dies and the absence ofall auxiliary stripping devices enables the machine to be speeded veryhigh.

I do not wish to confine myself to the exact location of the air-blastshown and described, as-said blast may be introduced immediately abovethe platform, in which case I would arrange the lower or spring diewithin the opening in the plate in such manner that the latter wouldform a seat for said die and enable the spring to be properly arranged,as in the manner shown in the drawings, and hereinbefore described. Thestripping would in this case be effected by the concussion ofthe edge ofthe box against the blanking-punch, and the airblast would carry off thecompleted box.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a machine for making boxes from paste or straw board, thecombination, with a cutting-punch and shaping-die arranged interiorthereof, of a plate having therein a seat for the punch, and an openingthrough which the said die passes, and a spring-actuated lower dieadapted to reciprocate within a corresponding opening and seat withinthe standard, substantially as set forth.

2. In a machine for making boxes from straw or paste board, thecombination, with the forming and cupping dies, of means, substantiallyas described, by which an air-blast is supplied to discharge the box.

3. The combination of the platform having therein at the lower centralportion thereof an internal recess, O, communicating directly with anaix-blast, plate C, secured to the platform immediately over saidrecess, and having seat N and central opening, D, punch L, havinginterior thereof the clipping-die M, said punch and die adapted to havea separate and independent vert-ical reciprocation, ring E, seatedwithin the standard B, and containing the lower die, G, spindle H,secured at its upper end to said die, and spring K, arranged around saidspindle and confined between recesses in said die and standard,substantially as shown, and for the purpose set forth.

In testimony whereofl affix my signature in presence of two witnesses.

ALBERT F. MOREE.
